Helium leak testing can be performed by either a Evacuation (Tracer Probe) or a Pressurization (Detector Probe).

You NEED Helium leak testing when:
  • Conventional methods do not work
  • There are recurring leaks on repaired systems
  • The item needs to remain moisture free while out of service
Why Helium?
  • It is the lightest of the noble gases with a mass of 4, only hydrogen is lighter
  • Helium is non-toxic and non-reactive
  • Trace concentrations (5ppm) present in atmosphere
  • Readily available and relatively inexpensive
